Innovation Solution
A terminal software upgrade method utilizing near-field communication (NFC) technology, where a near-field communication sensing circuit in the terminal is used to write boot-up and upgrade instructions, allowing the device to boot and upgrade software without manual operation, using a near-field communication instruction writing circuit to control the upgrade process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual intervention is used for software upgrade, then upgrade reliability can be ensured, but work cost increases and efficiency decreases
Solution Approach 1:
The terminal device performs self-upgrade by automatically detecting available updates, downloading them, and installing them without requiring manual user intervention. The system uses its own resources (processor, memory, communication module) to complete the upgrade process autonomously, thereby improving efficiency while maintaining reliability through automated verification and installation procedures.
Solution Approach 2:
The system performs preliminary actions by pre-checking for available software updates, pre-downloading them to local storage, and pre-preparing installation configurations before the actual upgrade process. This allows the terminal to be ready for immediate upgrade when triggered, reducing overall upgrade time and improving productivity.
2Productivity
If automated upgrade process is implemented, then work efficiency improves, but upgrade control and verification complexity increases
Solution Approach 1:
The upgrade control mechanism is segmented into distinct independent modules: update detection module, download management module, verification module, and installation module. Each module handles a specific aspect of the upgrade process, making the overall complex automated system more manageable and maintainable while improving efficiency through specialized processing.
Solution Approach 2:
The system implements feedback mechanisms where the verification module checks the integrity and compatibility of downloaded updates before installation, and the installation module provides feedback on upgrade status and success rates. This feedback loop allows the system to automatically adjust its behavior, ensuring reliable upgrades while maintaining controlled complexity through automated decision-making.
3Extent of automation
If near-field communication is used for instruction writing, then automation level increases, but communication distance requirement is introduced
Solution Approach 1:
The patent uses an intermediary device (such as a mobile phone or computing device) that acts as a mediator between the instruction writing circuit and the terminal device. The intermediary first stores the boot-up instructions locally and then transfers them to the terminal via near-field communication, allowing automation to be achieved while managing the limited communication distance through a multi-step process involving intermediate storage and transfer.
